Abstract

OBJECTIVE:

This study reports the efficacy of a cognitive behavioral outpatient treatment on interpersonal outcome variables for patients diagnosed with borderline personality disorder.

METHOD:

In a 1-year clinical trial, 26 female patients with borderline personality disorder were randomly assigned to either dialectical behavior therapy or a treatment-as-usual comparison condition. All subjects met criteria of DSM-III-R and Diagnostic Interview for Borderline Patients for borderline personality disorder and were chronically suicidal.

RESULTS:

In both the intent-to-treat and treatment completion groups, dialectical behavior therapy subjects had significantly better scores on measures of anger, interviewer-rated global social adjustment, and the Global Assessment Scale and tended to rate themselves better on overall social adjustment than treatment-as-usual subjects.
